To allwh'omit may concern:

Be it known that I, ALFRED KAUFMAN, a subject of the Emperor of Germany, and a resident of the city, "county, and State of New York, have invented certain new and useful Improvements in Hydrocarbonap or Generator and Burning Devices, of which the following is'a specification.

This invention relates to apparatus for generating gas fromhydrocarbon and for burning the gas. a a

The object of the present invention is a simple device which will burn hydrocarbon without the production of soot or disagreeable odor in an efficient and reliable manner for heating and lighting.

Another object "is the combination of the various elements in'such manner that maxi- I mum heat is'given with a minimum amount of fuel, and with'asfew movable parts as possible. I I

Another obj ect is a gasgenerating mechanism s'o arranged and operated as to prevent the deposit ofsoot on the essential elements thereof.

Specifically, apart of my invention con sists in a perforated plate arranged to be slid into positiona short distance'above the wick while the wick is'lighted and to be" slid into position through the non-luminous part of the flame which is, at that'tim'e, used to preliminarily heat the device, and therefore by 'means of the structure shown the perforated plate is placed in position without the dep'osit of any foreign matter, such as soot, thereon.

The above objects may be carried out by the means, or their equivalents, specifically described hereinafter and shown in the ac- I companying drawings, in which Figure '1 is a side elevation of the complete device; Fig. 2 is a section onrline 22 of Fig. 1; Fig. 3 is a section on line 33 of Fig. i, with the burner tube attached; Fig. 4 is a plan view of amodification with the burner tube removed Fig. 5' is a view of the perforated plate22; F i'ga 6 is a view of" the perforated plate 16; Fig. 7 is an enlarged view of the burner tube with the flame showing the part of the flame through which the plate 16 is passed; Fig. 8 is a I Patented Au 31,1915. 7

view similar to that of Fig. 7 with the perforated plate "1Q in position; and Fig. 9 is a modification showing a round wick and plate adapte'd tobe placed in position thereover. a

In the drawings, 1 represents a hydrocarbon fuel reservoir of any suitable shape and size/ In Figs. 1, 2 and '3 it is shown as rectangular and forms the-base of the device. -Rising from the reservoir is a wick tube 2 adaptedto accommodate a wide, flat wick, and of siifiicient length 'so that no substantial amount of heat will be transmittedtoth'e reservoir 1. Thistube may be soldered, or otherwise secured to the reservoir. In this tube is a wick 12 which is adapted to be raised or lowered by means of the thumb piece 3 in the well-known manner. I

, A table 4' having four projecting legs mountedon' top of the reservoir and 1s rigidly secured thereto by any suitable means. This table has a rectangular openingtherein in which is placed a rectangular member 5 having a frusto-pyramidal portion 14 adapted to be placed over the wick tube 2, but leaving a space between the inside of the part 1a and the'outside of the wick tube 2 sufficient for the entrance of enough air to produce a *blue flame along each of the sides of the wick, as will more fully appear hereinafter. A perforated plate 22- is'p're ferably placed in the opening between the portion M and the Wick tube so as to more evenly regulate the draft for the wick flame.

Arranged in the upper part of the portion 14 are guide ways 15 adapted to receive a perforated plate .16, which preferably extends entirely across thev opening in the portion 1 The position. of these guide ways, and therefore the plate, when in normal aosition is a short distance above 7 the top of the wick and is so situated that "when the perforated plate 16 is removed and the wickis lighted to preliminarily heat the device, "the perforated plate .16 can be slidinto position in the guide-ways through the non-luminous portion of the flame. This feature is ofconsiderable importance for the reason that the plate lGc-an be entirely removed from the device while it is being heated up, and can then be slid into position so as to stifle theflame, without its being necessary for the plate to pass through the luminous or carbon-carrying portion of the flame, whereby a deposit of soot would be inevitable. The height of the flame, and therefore the height of the nonluminous portion of the flame, can be regulated .by adjusting the position of the Wick by the thumb-piece 3, so that the plate can be placed in position through the nonluminous part of the flame, as above described.

The perforated plate 16 may be slid into position sidewise, that is to say, it may enter along one of the long sides of the flame and pass through it the short way. In the pres ent form of the apparatus it passes in endwise of the flame and this is the preferred way of'inserting the plate. .In the case of a round wick, as shown in Fig. 9, the screen [while being placed into position, will necessarily pass through the flame in both ways, because when it is first inserted it will pass sidewise through the flame and as it is pushed across the wick it will successively cone of which passes through each of the .pass through the flame lengthwise and then sidewise again. It has been found by numerous experiments that even though the perforated plate 16 be slid into position, it must be placed therein through the non luminous portion of the flame. If it is slid, or otherwise placed in position, through the luminous part of the flame, comparatively -large volumes of black smoke will be the result and the perforated plate will be heavily coated with lamp-black. On the other hand, if the flame is so adusted that the plate will .pass through the non-luminous portion, no black smoke whatever will be observed and no lamp-black or soot deposit will be made 1 on the plate. In placing the plate in position through the non-luminous portion of the flame it will be observed that the flame recedes a short. distance in front thereof through its entire course across the wick,

so that no soot whatever is deposited upon the plate. There is another advantage of c the removable feature of the plate 16in that, during the preliminary heating of the device, no vapor is deposited thereon whereby to it might become inefficient through the partial closing of the small perforations therein. Mounted above and on the part 14 is a mixing or burner tube 6. This tube may be secured to the part 14 by means of screws passing through projections 11 which'may be integral with the part 14, or it may be at tached in any other suitable way. This tube is preferably made up froma' cylinder of suitable material by flattening the lower portion of the cylinder into the shape shown the same as that for a flat wick, except, of 'course,'--its shape. This plate differs also in Figs. 1 and 2 and may be heat insulated if desired: The tube when completed has an elongated opening across the bottom, said the purpose of admitting air. The holes are preferably placed quite close to the plate 16 just above the same so that the air entering will come in at right angles to the course of the vapor or gas coming through the plate 16 whereby a complete mixture of the gas and air takes place. The air may be otherwise admitted to the tube 6 with satisfactory results. It will be noted that the plate 16 separates the wick chamber in the part 14v from the mixing chamber in tube 6, but for the communication through the perforations of the plate 16, so that there is a fuel chamber or reservoir, a wick chamber in the part 14 and a mixing chamber in the tube 6 all separate as above described.

Rising from the table 4 are four posts 8,

legs 13 and is secured thereon by means of nuts which are adapted to fit on the threaded portions of the posts 8.. The screw-threaded portions of the posts also go, into screwthreaded holes in the top of the reservoirv and serve to hold the table 4 and the parts supported thereby in position on the reservoir. Mounted on the top of the posts 81s a suitable plate 7, on which is mounted a grating 9 of ordinary construction. The

nuts which fit on the threaded portions of the upper ends of the posts 8. The length of the posts is such that the grating 9 comes a shortv distance above the top of the perplate 7 is secured to the postsby means of i forated plate 10 so that any article which may be placed upon the grating would be heated by the flame produced on the plate 10. The part 14, at one end, has a cut-away portion of sufficient size to permit the insertion of a lighted match or other means to ignite the wick when the plate 16 is removed. .The plate 16 has a down-turned portion 23 of suitable size to cover this openingduring the normal operation of the device. The,

portion 23 of the plate 16 acts as a handle by which it can be removed from and'placed into position. There is 'a chain 24 fastened to the plate 16 so that it may beremoved getting mislaid or lost. shown as a thin piece of perforated metal, but if it is found desirable it may be reinforced alongits sides in anysuitable' way.

The plate for use on round wicks is much from'the guidevways and be prevented from. The plate 16 is ,thierefrom inthat there is an opening in the "center'thereof, asshown in Fig. 9, in order that the wick flames may have sufficient airy burning'fora suiiicient time to burner tube and other parts, the plate16 is *slid i.nto-position through the non lumi nous part of the flame. When the plate 16 is in its normal position the flame is divided tosupport them.

The preferred shown in Figs. movable part, and thispart, the'plate 1b,

- positively. guided in its movements and 1s when used by those "firmly' held in position inthe device. f' This is an important feature of the device because there is nothing to get out of order unskilled in mechanical devices. The deviceillustrated in the drawings, which .were made from a full-size model, has been extensively operated over a long period of time, and has, in every instance, operated entirely satisfactorily.

The reservoir may be so arranged that it can be slid out from under the table 4. in order that the wick may be lighted and can then be placed back into position to temporarily heat the parts in which case no opening in the'portion 14: for lighting the wick, nor the downward projection of the plate 16, will be necessary. I This construction is shown in Figs. 3 and 4. j The essential parts of the device shown in these fi ures are the same as previously described. lhere are necessarily some changes by reason of which the burner may be removed from under the tube in order that it may be lighted. In this modification the base 18 has a sheet metal portion 19 rising therefrom. The posts 8 are fastened in this plate 19 by means of nuts. The table 4:has four posts 20 passing therethrough, which also may be fastened by bolts or otherwise to the plate 19. The table 1 is supported a short distance abovethe plate 19 in order that air ma be admitted through the perforated .plate 22 fastened to the bottom of the table 4. The part 19 has aportion cut away on one side thereof through which the reservoir 1 is adapted to slide, and the table 4 has an opening in one end thereof through which the wick tube passes. This perforated plate 22 also has anopening to accommodate the wick tube. Fastened on to the wick tube is a member 21 which is adapted to close the opening in the frusto-pyramidal part 141 of the table 4: in order to cut off any air which might otherwise enter When it is desired to light the lamp, the reservoir and wick tube are drawn out and the wick is lighted and adjusted and is then placed back in position in order to heat up the burner tube and other parts. The perforated slide plate 16 is removed with, or prior to the drawing out of the reservoir to light the wick, and is subsequently slid into position, as above described. With the above-noted changes, ates in the same way as the one previously described, and which operation is as follows :The plate 16 is removed, the wick form of my device, as 1, 2,6, 7"and8,has only one lamp is thus started it through this opening.-

this modification oper to give a smokelessfiame. After it has been into two small bluefiames along the outer "edges of the wick, which, by means of their ntense heat, vaporize the fuel drawn up by the wick. This vapor passes through the plate 16 into the lower part of the tube 6 and is there thoroughly mixed with the air coming in through the perforations at the bottom of the tube. By means of this arrangement the tube 6 can be wholly unobstructed, which adds to the efficiency of the device. This mixture of air and gas then passes through the tube 6 and is lighted above the perforated plate 10 at which point a blue non-luminous and odorless flame is produced which has very high temperature. The amount of vapor and therefore the size of the flame on the plate 10 can be increased or decreased by moving the wick up or down by means of the thumb-screw 3. WVhen the will operate indefinitely unless it is purposely extinguished.

Having described my invention, what I heat up the claim as new, and desire to secure by Letters at the upper end of said chamber.
